Gastritis facts

  • Gastritis is inflammation of the stomach lining and is usually termed acute or chronic gastritis.
  • The two major causes of gastritis are 1) a bacterium named Helicobacter pylori or H. pylori and 2) nonsteroidal anti-inflammatory drugs (NSAIDs). However there are many other causes like other infectious agents, autoimmune problems, diseases like Crohn's disease, sarcoidosis, and isolated granulomatosis gastritis.
  • Although many individuals with gastritis may have no symptoms, both acute and chronic gastritis may have symptoms of
  • Gastritis can be diagnosed by the patient's symptoms and history (for example, NSAID and/or alcohol consumption), or by breath, blood, stool, immunological, and biopsy tests to detect H. pylori and other tests such as endoscopy or radiologic studies demonstrate mucosal changes.
  • The treatment for gastritis varies according to the cause.
    • H. pylori usually is treated with a combination of antibiotics.
    • NSAID's are treated by stopping the drug and using antacids, histamine blockers or proton pump inhibitors or PPIs, for example, omeprazole (Prilosec, Prilosec OTC), omeprazole (Prilosec, Prilosec OTC), rabeprazole (Aciphex), rabeprazole (Aciphex), esomeprazole (Nexium), and Zegerid, a rapid release form of omeprazole.
    • Other less common causes may be treated similarly, but do not treat the underlying cause.
  • Home remedies (for example, over-the-counter antacids or histamine blockers) for gastritis usually do not treat the underlying cause, but reduce symptoms.
  • Foods and chemical irritants that cause or aggravate gastritis symptoms should be reduced or stopped all together. For example:
    • Stop cigarette smoking.
    • Avoid drinking excessive amounts of alcohol.
    • Avoid caffeinated, decaffeinated, and carbonated dinks; and fruit juices that contain citric acid, for example, grapefruit, orange, pineapple, etc.
    • Avoid high-fat foods.
  • The growth of H. pylori may be stopped by a diet rich in fiber, and foods that contain flavonoids, for example:
    • Certain teas
    • Onions
    • Garlic
    • Berries
    • Celery
    • Kale
    • Broccoli
    • Parsley
    • Thyme
    • Soy foods
    • Legumes
  • Complications from acute gastritis are rare.
  • Complications from chronic gastritis include peptic ulcer, bleeding ulcers, anemia, gastric cancers, MALT lymphoma, renal problems, strictures, bowel obstruction, or even death.
  • People with acute gastritis usually recover completely with no complications.
  • Chronic gastritis may have a range of outcomes from good (early treatment) to poor if serious complications develop.
  • If underlying causes of gastritis (for example, alcohol or NSAID's usage) are treated or not used, gastritis also may be prevented.
  • Other gastritis prevention techniques include:
  • To prevent infectious causes of gastritis practice good hand washing techniques, for example, wash the hands thoroughly and frequently.
  • To reduce the risk of gastritis avoid situations where you are exposed to chemicals, radiation, or toxins.
